  34 <PRE>Greetings all,
  35
  36 Problem:
  37 -------
  38         Installing gcc 3 i notice a strange behaviour at the services.
  39 The problem is specified at two functions inside misc.c. The functions
  40 are strupper and strlower. The exact problem is at:
  41
  42 char *strupper(char *s)
  43 {
  44     char *t = s;
  45     while (*t)
  46         *t++ = toupper(*t); &lt;-
  47     return s;
  48 }
  49
  50
  51 According ANSI C spec, &quot;... C expressions can contain side effects,
  52 issues of sequencing are important in expression evaluation.&quot; (2.1.2.3)
  53
  54 Results:
  55 -------
  56 The result of this code is to have &quot;random&quot; effects while using services.
  57
  58 Example:
  59 -------
  60 /quote version services.test.irc.gr
  61 11:25 ## Server services.TEST.irc.gr: ircservices-4.5.21 build #1,
  62 compiled Sat Jul 14 23:01:42 EEST 2001

  76 Solution:
  77 --------
  78 I guess strupper and strlower should be rebuid. For those looking for one
  79 fast solution, i can post one.
